MAX6793TPLD4+

Supervisors Overview

The MAX6793TPLD4+ is a dual-output linear voltage regulator from the MAX6791–MAX6796 series, designed for automotive applications. It features a wide input voltage range of 5V to 72V and consumes only 68µA quiescent current. Each output channel supplies up to 150mA with adjustable or fixed output voltages ranging from 1.8V to 11V. The device integrates supervisory functions including a watchdog timer and power-fail monitor. It operates within an extended temperature range of -40°C to +125°C and is housed in a 20-pin TQFN-EP package.

Supervisors Feature Summary

• Ultra-low quiescent current consumption ideal for battery-powered systems
• Wide operating input voltage range withstands automotive load-dump conditions
• Integrated supervisory circuitry with configurable watchdog timeout periods
• Dual-channel architecture providing independent positive regulation

Supervisors Applications

• Automotive electronic control units requiring high-voltage tolerance
• Battery management systems minimizing standby power drain
• Noise-sensitive sensor interfaces utilizing low-noise linear regulation
• Industrial control modules operating under extreme temperature variations

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance and lead-free specifications match project requirements. Check datasheet revision history for any pinout or electrical parameter updates before finalizing design integration. Ensure thermal management aligns with specified power dissipation limits in the target enclosure.

Supervisors Selection Notes

Select this component when designing circuits requiring simultaneous dual-rail regulation from high-voltage sources. Consider the 68µA quiescent current for strict energy budget constraints. Evaluate the 150mA per channel limit against peak load demands. Verify that the 20-TQFN package fits the available PCB real estate and thermal pad requirements for adequate heat sinking.

Supervisors Part Context

Part of the MAX679x family of micropower regulators combining linear regulation with supervisory logic. This specific suffix indicates a dual-output variant with a TQFN-EP package. It complements single-output models like the MAX6795/6796 which offer higher current but lack dual channels. The series targets robust performance in harsh electromagnetic environments typical of modern vehicle architectures.

Supervisors Replacement Considerations

Direct substitutes include other MAX679x variants such as MAX6791 or MAX6793 with matching output configurations. Cross-reference pinouts carefully as package types may vary between TQFN and QFN options. Ensure equivalent input voltage ranges and quiescent current specifications are maintained for system compatibility.
